may 19, 1997 - Out of Sight

Description:

In the changing rooms, a student hears a girl laughing, but sees nothing, before being beaten with a baseball bat. Later, a girl falls down the stairs but claims she was pushed, although nobody sees who pushed her. Cordelia rescues her English teacher from suffocation. Buffy hears a flute playing, and deduces that Marcie, a flautist who disappeared some months ago, has become invisible and is behind the incidents. Separately, Angel tells Giles that he has been collecting material on The Master for decades, and he will let Giles see it. Giles suggests that Marcie became invisible as a direct result of being ignored by everybody at the school. Cordelia asks Buffy for help, and confesses that, despite being popular, she often feels alone. Marcie traps Xander, Willow, and Giles in the boiler room filling up with gas. Angel rescues them before giving Giles the research materials. Marcie kidnaps Cordelia and Buffy, taking both to The Bronze and tying them up. Marcie plans to disfigure Cordelia's face, slashing it once before Buffy breaks loose. Initially hampered by being unable to see Marcie, Buffy focuses and defeats her. Men dressed in black arrive and take Marcie to a class with other invisible people, to learn about assassination.
